10 Claims. (01. 219 z5) An object of my invention is to provide a sadiron construction of simple, durable and inexpensive construction.

A further object is to provide a comparatively 5 inexpensive sadiron construction especially adapted for small, light weight irons, such as tourists irons, a novel terminal connection be.-

ing provided and especially adaptable for a light weight iron of this character.

A further object is to provide a sadiron construction composed of a plurality of parts readily assembled relative to each other on a single stud of the sole plate.

A further object is to provide a terminal con- 15 struction forv sadirons comprising a terminal plate having a flange on which the terminal pins are mounted with the pins extending laterally relative to the iron.

Still a further object is to provide a guard for l the terminal pins which effectively guards against accidentalcontact of the operator therewith and effectively encloses the terminal pins in such manner that a connector plug for association therewith can extend laterally from; the iron 25 without monopolizing the space behind the iron handle usually occupied by such connector plug.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the de- 0 vice, whereby the objects contemplated are attained, as hereinafter more fully set forth; pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure l is a plan view of a sadiron construction embodying my invention.

Figure 3 is a sectional view on the line 3-3 of Figure 1 showing the parts on a slightly enlarged scale. a 40 Figure 4 is a plan view with the handle support broken oil? just above the shell, part of the shell broken away and all but the retaining ears of a guard for the'termirial pins broken away.

Figure 5 is a perspective view of a terminal plate or bracket used in my sadiron construction.

Figure 7 is a side elevation, of the rear end of the iron as seen from the left side thereof; and

.30 Figure 8 is a side elevation from the right side showing most of the iron in section.

On the accompanying drawings I have use dv the reference numeral [0 to indicate a sole plate. The sole plate In is provided with a heating ele- 55 merit groove l2 in which is mounted a heating element A. The element A may consist of a coiled resistance wire l4 embedded in argillous material heating element A in position in the groove l2. This cover plate has a perforation indicated at 22 to receive the stud ID. A terminal bracket T is also mounted on the stud and the bracket '1 and plate 20 are retained in position bya nut 24. 5 Above the nut 24 a spacer 26 is provided which is surmounted by a handle support HS.

A shell S is provided for enclosing the parts of the sadiron above the sole plate in and it is retained in position by a retainer nut 28. When the nut 28 is tightened in position, it retains the shell S, the handle support HS' and the spacer 26 tightly against the nut 24 and thus holds all theparts in assembled position.

The cover plate 20 is positioned on the sole plate In and retained against rotation by a pair of lugs 30. The .cover plate is provided with notches 32 to receive these lugs. A third lug 34 is provided at the front end of the sole plate [0. All three of the lugs and the side edges of the plate 50 20 serve to position the shell S. relative to the soleplate l0.

The heel or rear end of the shell S indicated at 36. is also positioned laterally by the rear terminal edge of the plate 20 which is preferably turned up in the form of a flange 38 fltting between the sides of the shell S. The portionoi the plate 20 extending beyond the rear terminab edge of the sole plate it serves as a closure for the heel 36 of the shell S. w

The terminal plate T has a foot portion 40 provided .with a perforation 42 to receive the stud I8. Back 01' the foot portion 40 the terminal plate is oiIset upwardly and the major portion of the plate, indicated at 44, slopes rearwardly and 5 terminates in a tongue 48. The tongue 46 'extends through a slot 48 in the plate 20 to retain the terminal plate T against rotation around the stud Ill. The plate T has an upstanding flange 50 provided with a pair of perforations 52. Ter- 40 minal pins 53 extend through the perforations 52 and are suitably insulated relative thereto and retained in'position by nuts, as shown in Figure 3. A plurality of flanges 54 and 56 are provided on the flange 50 to reinforce it against bending. 46

the sole plate and slants slightly from the ver- 50" tical. Accordirmly theterminalpins 53 slant upwardly and outwardly relative to the sole plate. The shell S has'an opening Glt'for the flange 50 and the terminal pins 53. One edge of this opening is provided with a flange 62 slanting down- 5 wardly and inwardly (see Figure 3').

A guard G is provided for the terminal pins and the flange 50 which is archedover these parts and for ornamental purposes is made in a streamline shape as shown by dotted lines in Figures 1 60 and 4. The guard'G has a plurality of tongues ply cord extends for coaction with the terminal pins 53.

The handle support HS is of the shape shown in Figure 6. In cross section it is channel shaped and has a perforation at ll receiving the stud' and a downwardly extending sleeve of the retainer nut 28. The lower end of the handle support HS is mounted inside the shell S and extends upwardly through a channel shaped slot 12 therein (see Figure 4). The upper end is perforated as at 14 to receive a lag screw 16 extending into one end of a handle H. The handle may be'of wood or any suitable composition.

The handle H has a rear face I8 which contacts with a bump or rib 80 formed on the handle support HS. Whenever there is ironing pressure on the handle II, it is transmitted to the rib 80 and this transforms the strain on the lag screw 16 from a bending strain to a tensioning strain, thus providing a connection of the handle H to the sadiron, which is much longer lasting than the ordinary type. v

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover 'by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
